When my old phone s6 coupled to my superb it made a audio noise now my new phone connects but no sound 

Did connection sound come from phone or car? If phone i think it’s phone feature then, you should see from your infortainment system that phone is connected  

 

I have iPhone and it doesnt make any sound etc when connecting to car.

If it is specific to the Superb, this is the Octavia forum, I know some Superbs has RASP connections so that could be the difference.

What age is your Superb?  When I was looking at Superbs around 2010 it was a feature on the Bluetooth that was not supported by iPhones that gave the car more control and allowed the phone to use the car aerial rather than phone one.  It meant iPhones could not connect via Bluetooth.

 

As said this is the Octavia forum rather than Superb so there may be more information on that forum.
